TUBULAR Lanrnnn.

Patented Feb. 2, 1909.

To all whom it may concern:

Be it known that I, FREDERICK K. WRIGHT, a citizen of the United States,and resident of Syracuse,in the county Onondaga and State of NewYork,have invented a new and useful Improvement in Tubular Lanterns, ofwhich the following is a specification.

This inventionrelates to' the tubular lamps or lanterns in which theflame issues through a slot in the burner cone and the latter issurrounded by a perforated plate on which the globe rests and throughwhich the outside air enters the globe around the burner cone. It isoften found in lamps and lanterns of this kind that the flame becomesflaring or drawn out at'its ends far beyond the body of the flame. Thesedrawn-out end portions of the flame often generate considerable smoke,while the body of the flame is smokeless, and this .smoke is depositedto a greater or less extent on the globe opposite the ends of the flameslot. When the flame assumes this objectionable form the difficulty isusually sought to be overcome by trimming off the corners of the wick,but this does not always secure the desired effect.

The object of my invention is to provide the lamp or lantern with meanswhereby this difficulty is avoided. For that purpose I provide the globeplate with deflectors opposite the ends of the flame slot, whereby theair issuing with the flame from the ends of the flame slot is confinedand prevented from spreading and the flame is thereby confined at theends and prevented from flaring or becoming drawn out.

In the accompanying drawings: Figurel is a perspective view of the lowerportion of a tubular lantern provided with my improvements. Fig. 2 is asectional elevation of the burner and globe plate, on an enlarged scale,the section being taken lengthwise through the flame slot. F ig..3 is anelevation of a tubular lantern embodying this invention.

Like letters of reference refer to like parts I in the several figures,

A represents the oil pot of a tubular lamp or lantern of any suitable orwell known construction, B the air chamber upon the oil pot, C the airtubes connected with the air chamber, E the burner seated on the oil potand provided withtheusual wick tube e, F the burner cone seated on theair chamher and provided above the upper end of the jfrom'turning aroundthe burner cone.

wick tube with the usual flame slot f, and G the globe plate whichsurrounds the burner cone and rests upon the shoulder thereof.

H represents deflectors which are secured upon the globe plate in linewith the flame slot and which project upwardly from the globe plate at ashort distance outside of the burner cone. The upper portions of thesedeflectors stand opposite the ends of the flame slot and at such adistance therefrom that the air current issuing from the end portion ofthe flame slot strikes the deflector and is thereby deflected upwardlyand prevented from spreading laterally. The flame is therebypreventedfrom becoming drawn out and smoky at the ends and the globe is keptclean and free from smoke.

The upper ends of the deflectors are preferably curvedoutwardly, asshown at h. The globe plate carrying these deflectors is held in theproper position with reference to the flame slot by any well known orsuitable device which preventsthe globe plaIte n the construction shownin the drawing the lantern is one of the well known kind in which theglobe plate is attached to upright side wires h by which the plate ismoved up or down'and which prevent the plate from turning on the cone.The latter is prevented from turning on the air chamber by any of theusual contrivances, for instance, in the usual way by the wick-raisershaft 71.

I claim as my invention:

1. The combination of a burner comprising a wick tube and a burner conewhich surmounts the wick tube and is provided with a flame slot abovethe same, a. globe plate which surrounds the cone and is movable towardand from the burner, upright deflectors secured to the globe plate andarranged Outside of the cone and opposite'the ends of the flame slot,and means for holding the globe plate with its deflectors in line withthe burner slot, substantially as set forth.

2. The combination of a burner comprising a wick tube and a cone whichsurmounts the tube and is provided with a flame slot above the same, aperforated globe plate surrounding the cone and movable toward and fromthe burner, and deflectors arranged on said plate and extendingtherefrom upwardly opposite the end portions of the flame slot,substantially, as set forth.

3. The combination of an oil pot, 711 air the end portions of the flameslot, substan- JO chamber on the same, a b urneriseated on the tiallyasset forth. oil'pot' and provided 'With Wick tu'be,' af 'Witne'ss myhand, this 14th day of May, burnecrl' eione ieatecili on thle airchamber amp]. I 1904.
